CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 250,172, dated November29, 1881.

Application filed July 5,1881. (ModeL) To all whom it may concern Be itknown that I, BRADFORD SEWALL, of Farmington, in the county of Franklinand State of Maine, have invented an Improved (Jan-Filling Machine, ofwhich the following is a specification.

The object of my invention is to provide a new and improved machine forfilling cans rapidly without any waste, and which feeds and carries offthe cans automatically.

The invention consists in a can-filling machine composed of a table onwhich a radiallywinged wheel is pivoted, between which wings the canspass from the lower end of an open cylinder containing a stock of cans,and are carried under the nozzle of a cylinder, which isheld in a raisedposition byaweight attached to the outer end of a lever acting on thecylinder-frame, and in which cylinder a piston fits, which is suitablyguided and actuated by a rod connected with a lever, to which a slidingbar is also connected, sliding under the table, and provided with apawl, which rotates the can-carrying wheel.

In the accompanying drawings, Figure 1 is a plan view of my improvedcan-filling machine. Fig. 2 is a longitudinal sectional elevation of thesame on the lineman, Fig. 1. Fig. 3 is a cross-sectional elevation ofthe same on the line 3 y, Fig. 1. Fig. 4 is a cross-sectional elevationof the same on the line 2 2, Fig. 1.

Similar letters of reference indicate corresponding parts.

A wheel, A, provided with a series of radial wings, B B, is pivoted torotate in a horizontal plane on a table, 0, under which a bar, D,slides, provided with a pawl, E, which catches on the wings B B, andthus rotates the wheel A. The rear end of the sliding bar D is pivotedto an upright arm, F, of a swinging lever, G, attached to a transversebar, H, pivoted in the frame of the machine. The lever G is provided atits front end with a handle, J, for operating it. A rod, K, attached tothe lever Gr,-

extends upward, is bent at right angles, and passes into an aperture inthe piston-rod L, which is guided to slide vertically on the trans-Verse bars M of the uprightframe of the machine. A piston, N, isattached to the lower end of this piston-rod L and fits in a cylinder,

or nozzle, P, which fits into apertures in the cans Q. The cylinder 0 isattached to a frame, R, sliding and guided on the upright part of theframe of the machine. The lower end of a board or bar, S, extendingdownward from the frame R, is pivoted to a pivoted lever, T, having aweight, U, attached to its outer end, which weight serves to hold theframe B and the cylinder 0 in a raised position. A number of cans, Q,are held one above the other in a vertical cylinder, V, of any desiredheight, and attached to the vertical part of the frame of the machine'insuch a manner that the cans, passing from the lower end of this cylinderV, will pass in between two wings B B of the wheel A.

The table 0 is provided with a series of apertures, V, through which thewaste material drops.

The guard-plate Y prevents the cans from being forced from the table andforms a curved track, along which the cans slide.

The operation is as follows: If the handle J is raised the piston N isdrawn out of the cylinder O and the pawl E moves the wheel A in thedirection of the arrow at. One of the wings rests against the lowest canQ of the column of cans in the cylinder V and carries it along, thuscausing all the cans in the cylinder V to drop the distance of one can,and the cans will be thus successively carried off by thewheel A. Thecans are thus carried under the cylinder 0, into which the material thatis to be filled into the cans is passed. By depressing the handle J theplunger or piston N is pressed into the cylinder 0', and the cylinder isthus lowered, the spout or nozzle P passing into an aperture in the topof the can. By further depressing the handle J the piston forces all thematerial from the cylinder into the can. If the handle is raised anempty can is carried under the cylinder and the filled can is carriedaway and thrown outward by the wheel A. As theweight U raises thecylinder 0 as soon as the piston is raised, the wings B cannot strikeagainst the lower end of the spoutl Having thus described myinvention, Iclaim as new and desire to secure by Letters Patent 1 In a can-fillingmachine, the combination, with the table O, of the guard-plate Y and thewheel A, provided with radial wings B, substantially as herein shown anddescribed, and for the purpose set forth. 7

2. In a can-filling machine, the combination, with the table 0, 0f theguard-plate Y, the wheel A, provided with radial wings B, and thecanreceiving cylinder V, substantially as herein shown and described,and for the purpose set forth.

3. In a can-filling machine, the combination, with the piston' N andcylinder 0, of the rod K, the levers G and T, the frame It, and thestrip or bar S, and the weight U, substantially as herein shown anddescribed, and for the purpose set forth.

4. In a can-fillin g machine, the combination, 1 with the table 0, ofthe guard-plate Y, the wheel A, provided with radial wings B, thecan-receiving cylinder V, the cylinder 0, the piston N, the rod K, thelevers G and T, the weight U, the bar D, and the pawl E, substantiallyas2o herein shown and described, and for the purpose set forth.
